Troubleshoot:
Use the scripts/paw.ps1 script instead of Administration tool from power shell prompt.
Enter scripts/paw.ps1 to ensure all services are running and up-to-date.
Enter scripts/paw.ps1 ps to see status of all services.

Above may show that you have a pa-gateway already running.
Check that no other application is using port 80 and 443.
Start IE on the server and surf to http://localhost/ – what does that give?

Stop all PAW with scripts/paw.ps1 down
Then start it again with scripts/paw.ps1

Did it help?

Enter docker ps -a to see all running containers. Any duplicates?
Then to remove a container enter docker stop <container-id> ; then docker rm <container-id>.

Check the log files in folder D:\install\paw\log\pa-gateway\error.log
If you see this; AH00558: httpd.exe: Could not reliably determine the server’s fully qualified domain name, using fe80::5db7:f898:8a1:858c. Set the ‘ServerName’ directive globally to suppress this message. Then that is nothing to be concerned about.

You can recreate the docker network with below commands (try this first):
Stop the docker service: stop-service docker
Make sure the hns service is running: start-service hns
Now run this PowerShell command: get-containernetwork | remove-containernetwork
Start the docker service again: start-service docker

If it still doesn’t work, you can also try the same steps except with get-netnat | remove-netnat:

Stop the docker service: stop-service docker
Make sure the hns service is running: start-service hns
Now run this PowerShell command: get-netnat | remove-netnat
Start the docker service again: start-service docker

After that is done, go to the d:\install\paw\scripts folder in power shell.
Start the PAW with ./paw.ps1 start.

Check the file D:\install\paw\config\paw.ps1 contain the values you have set in the administration tool before. Should look similar to this;
# paw.ps1 file generated by the Administration Tool
$env:TM1Location=”https://labwin2012ca.lab.local:5898″
$env:TM1ApplicationsLocation=”http://labwin2012ca.lab.local:9510″
$env:PAAuthMode=”tm1basic”
$env:TM1LoginServerURL=”https://labwin2012ca.lab.local:8010″

Surf to servername to see if paw is working e.g. http://labwin2012ca.lab.local/

To get more detail debug info on screen,
stop the docker service.
Run the Docker daemon in debug mode:
C:\Program Files\Docker\dockerd -D
